6 x 2 = 12

(i) In Python, a set is another type of collection data type. A'Set is a mutable and an unordered collection of elements without duplicates.
(ii) That means the elements within a set cannot be repeated. This feature used to include membership testing and eliminating duplicate elements.

Syntax:
# Tuple with n number elements
Tuple_Name (E1, E2, E3.......En)
# Elements of a tuple without parenthesis
Tuple_Name = El, E2, E3 ................. En

	del function	remove () function
(i)	del statement is used to delete elements whose index is known.	move( ) function is used to delete elements of a list if its index is unknown.
(ii)	The del statement can also be used to delete entire list.	The remove ( ) function can be used to delete one or more elements if the index value is not known.

Python enables reverse or negative indexing for the list elements. Thus, python lists index in opposite order. The python sets -1 as the index value for the last element in list and -2 for the preceding element and so on. This is called as Reverse Indexing.

A list in Python is known as a "Sequence data type" like strings. It is an ordered collection of values enclosed within square brackets [ ]. Each value of a list is called as element.
